Answer:
105
Step-by-step explanation:
Supplementary angles are two angles that add up 180 degrees.
if one is 75, then the other would be 105
hope this helps :)
(i made a mistake so i edited it, thanks for the reminder in the comments)
105 degrees
Supplementary Angles are angles whose measurements equal 180 degrees
To find the supplement subtract this known measurement angle A
180 - 75 = 105 degrees

2x+y=3
6x=9-3y
-------------
y=3-2x
6x=9-3(3-2x)
6x=9-9+6x
6x=6x
infinitely many solutions
2x²-7x
7x²-5x²=2x²
10x-3x=7x
